COMBINATION-TOOL.

SPECIFICATION forming part of Letters Patent No. 560,824, dated May 26, 1896. Application fil d October 30, 1895. Serial No. 567,405. (No model.) Patented in England May 13, 1893, No. 9,576.

To all whom it may concern.-

Be it known that I, ARTHUR ALBERT TAT- 'TERSALL, a subject of the Queen of Great Britain, and a resident of the town of Blackburn, county of Lancaster, England, have invented certain new and useful Improvements in Combination-Tools, (for which I have obtained a patent in Great Britain, No. 9,576, bearing date May 13, 1893,) of which the following is a specification.

This invention relates to a-tool which combines in one a ratchet, a crank-brace, and a drill.

In carrying out my invention I make the tool in three separate parts,the first part being a crank-arm, the second a ratchet, and the third a drill. The ratchet or the drill can be used alone, or the crank and ratchet, or all the parts can be combined together so as to form one tool; and in order that my said invention may be properly understood I have hereunto appended two explanatory sheets of drawings, whereon- Figures 1 to 9 show different forms of the combination-tool.

On the drawings the same reference-letters, Wherever repeated, indicate the same or similar parts.

In Fig. 1 a combination-tool is shown consisting of a bent or cranked bar a, having at one end a boss at, provided with a vertical taper-socket, and at the other end a boss a, provided with a central vertical socket a and two horizontal holes a a at right angles to each other. The holes a and a are square, while the hole a is tapped for a pinchingscrew 1'. A ratchet b, having a short arm I) with a square endb is fitted into the horizontal hole 0!. of the boss a while the lower tapered end of the spindle c of the drill ois fitted into the tapered hole in the boss a. This drill, which may be otherwise of the usual construction, is made with a cranked or bent pap or stud 0 which is fitted to and capable of sliding up and down the spindle-c. The stud is clamped to the spindle by the The driving gear-wheel o is mounted on the extremity of the bent part of the stud, as shown.

The object of making the stud bent, as shown, is to support the wheel 0 at an angle so that it will clear the boss at of the brace,

' or the boss bof the ratchet if the drill is by the handle 0 or it may be turned by the crank a and be used in the same manner as an ordinary brace. When it is used as a brace, the ratchet part 17 should be turned around to a position at right angles to that shown, so that the screw 01 would not penetrate the body or breast, and the ratchet-head would be thus made to serve as a breastplate. If so desired, the parts can be taken asunder and the drill-spindle c be fitted into the ratchet b in the same manner as shown with an on dinary ratchet at Fig. 3. In this case the tool serves as a ratchet with a short lever-arm; but the arm can be lengthened by securing the crank a, to it, as shown at Fig. 9. In this case the ratchet-feed would be put on by the screw d in the ordinary manner.

As will be seen, the lower end of the drill- V spindle c is made with a point or center 0 on it, against which, in certain positions of the drill when used alone and where sufficient around to a position at right angles to that shown, serves the purpose of a breastplate. The head is removably secured to the crank a in the same manner as the ratchet-arm, Fig. 1-11. e., by being fitted in the hole a in the head of the crank a and secured therein bya pinching-screw c. In this case the tool can be used either as a cranked brace or as a drill.

In Fig. 3 the drill is shown as fitted in an ordinary ratchet b and the pressure is applied by turning the screw cl of the ratchet. As will be readily understood, the tool can in this case be used either as a ratchet or as a drill. The drill may in the same manner be fitted to any ordinary brace.

ICO

When the drill is to be fitted in a brace or a ratchet, the spindle has its lower tapered end squared, so as to fit into and turn with the drill-holder of the brace or the ratchet. The lower extremity of the spindle will preferably, in all cases, be made with a center or point 0, as at Fig. 1.

Fig. 4c shows the drill fitted into the ratchet b of Fig. 1 instead of into the crank a. In this case, as shown, the crank a is reversed and the screw 01 is removed from the ratchet and inserted in the boss a of the crank, which may be tapped for its reception. The feed is put on by the screw d. The tool can in this case be used at will, either as a drill, a ratchet, or a brace.

Fig. 5 shows a double-speed driving-wheel as fitted on a pap or boss 0, made in one with or secured to the boss at of the brace. The spindle 0 may in this case be round and be provided with a steel point or center 0 at its lower end. The spindle c is secured to the boss by a pinching-screw e. The Wheel c may be supported on the pap e by a washer c and screw a In Fig. 6 a breast-drill spindle f is shown as fitted on the spindle c of the drill as an extension. The drill, as shown, is made so as to fit any ordinary brace or ratchet, and the lower end of its spindle is cut with a screwthread. The breast-drill spindle is made with a hollow part f, which is tapped, as shown, for the reception of the screwed end of the spindle c. lVhen the center or point j of the breast drill attachment is placed against something stationary, the part f can be turned around in the same manner as an ordinary ratchet, so as to give the necessary feed. Lever or other pressure can be brought to bear on the point j of the breastplate. The screw 0 can in this case be provided with a handle 0 As will be seen, the drill can be used with the attachment in the same manner as an ordinary breast-drill.

Fig. 7 shows a removable lever-handle g, which may be fitted on the ratchet part b so as to give greater leverage. The handle is made with a socket g, into which the ratchetarm is fitted and held in place by a pinchin gscrew g To make the tapered spindle c of the drill part of the tool lit a ratchet square hole and a joiners-brace square hole, a connectingpiece m, Fig. 8, must be used. The end m of the connecting-piece fits into the joiners brace.

This combination-tool can be used for various purposes, as it combines practically three toolsviz., a crank-brace, a ratchet, and a drill. The parts can be taken apart and used separately, if so desired.

With the tool holes can be easily bored in metal from one-sixteenth of an inch to one and one-quarter inches.

The device is equally applicable for drilling as a drill or boring as a ratchet or a brace.

I'Iavingnow fully described my invention, what I claim, and desire to secure by Letters Patent, is

1. In combination, a crank-frame provided with sockets at its opposite ends, a spindle mounted in one of said sockets, a rotatable socket on said spindle, provided witha gear, a driving-gear adapted to mesh with the gear on said rotatable socket, and a ratchet mechanism carried at the opposite end of said frame, substantially as described.

2. In combination, a crank-frame provided with sockets at its upper and lower ends, a spindle mounted in the socket at the upper end thereof, a rotatable socket on said spindle provided with a gear, and a driving-gear adj ustable relatively to the gear on said socket, substantially as described.

3. In combination, a frame provided with a socket, aspindle mounted therein, a rotatable socket on said spindle provided with a gear, and a driving-gear mounted on said spindle with its body standing at an angle to said spindle, substantially as described.

4. In combination, a crank-frame provided with sockets at its upper and lower ends, a spindle mounted in said upper socket, a rotatable socket on said spindle provided with a gear, a drivin g-gear adjustable relatively to the gear on said rotatable socket, and an adj ustable ratchet mechanism carried by the lower end of said crank-frame, substantially as described.

5. In combination the crank a with its boss a with tapered hole for the reception of a drill-spindle and a boss a with a hole for the reception of the arm of a ratchet, the ratchet b with its arm 1) adapted to fit in the hole of the boss a and the drill c with its adjustable bent stud c and angled bevel-wheel 0 made with a spindle 0' adapted to fit in the hole in the boss a, substantially as hereinbefore set forth.
